2 Claims.

This invention relates to a pump by means of which water and other liquid may be forced upwardly to an elevated place of use from a source of supply.

pump of such construction that it is particularly adapted for use in irrigation systems for forcing water upwardly from a well or river or similar body of water to such a height that'the water i may be delivered to a main irrigation ditch.

Another object of the invention is the provision of a pump of such construction that water is forced by a plurality of impellers into the inlet pipe or neck at the lower end of a vertically disposed column through which the water passes and is discharged through a spout or other suitable outlet at the top of the column.

Another object of the invention is the provision of a pump of this character wherein the impellers are carried by a vertically disposedrotatably mounted shaft extending through a tube from which the inlet pipe of the column extends, the impellers being located above and below the inlet pipe and serving to urge Water from opposite ends of the tube towards the inlet neck or pipe of the column. It will thus be seen that one impeller will urge water upwardly through the tube to the neck while the other urges downwardly through the tube to the neck and strain exerted will be such that wear upon a bearing rotatably mounting the lower end of the shaft will be prevented.

Another object of the invention is to provide a pump of this character which is quite simple in 35 construction and consists of a comparatively few number of parts, all of which are strong and durable and not liable to easily get out of order.

The invention is illustrated in the accompanying drawing, wherein Figure l is a sectional view taken vertically through the pump, and

Figure 2 is a sectional view taken transversely through the pump along the line 22 of Figure 1.

This improved pump is particularly adapted for use as means for supplying water to an irrigation system and includes in its construction a column I which extends vertically and may be of any height and diameter desired. A discharge spout 2 is provided at the upper end of the column and may extend in any direction desired so that water forced upwardly through the column will flow through the spout and into a trough leading to an irrigation ditch or the spout may overhang the ditch for direct delivery of water One object of the invention is to provide a into the ditch. The lower portion 3 of the column is of solid formation to impart weight tothis lower portion and cause the column to be firmly supported in its upright position when the outstanding annular flange 4 at the bottom. of the column is secured to the base 5 by bolts h. At the top of the solid portion 3 the column is formed with an inlet from which an inlet neck '5 projects, and referring to Figure 1 it will be seen that the inlet neck communicates with a tube midway the length of the tube. This tube 8 D extends vertically over a portion of the base which projects from the lower end of the column and since the tube is open at both its upper and lower ends water may enter the tube from both ends for passage in opposite directions through the same to the neck l through which it flows into the hollow column. The water is to be forced through the tube from its opposite ends towards the neck 1, and in order to do so, there has been provided a pump shaft 9 which extends vertically axially of the tube and has its lower end mounted in a bearing it carried by the base 5. Spiral blades H and it are carried by the pump shaft in upper and lower portions of the tube 8, one blade being a righthand spiral andvthe other a left-hand spiral. It will thus be seen that, when the pump shaft is rotated, the two impeller blades El and i2 Will act in opposite directions and force water in end portions of the tube 8 towards its center and from the tube through the neck .1 for passage upwardly through the column. This not only permits water to. be fed from both ends of the tube to the neck but also equalizes' longitudinal stress upon the shaft and reduces wear upon the bearing H! and the portion of. the shaft engaging the same. Upper and lower bearing brackets l3 and it extend from the column 5 at a convenient distance from the level of the water and carry bearings and it in which the upper portion of the pump shaft is rotatably mounted; A pulley H is firmly secured upon the pump shaft between the bearing brackets for engagement by a belt l8 which serves to impart rotary motion to the pump shaft when a motor engaged by the belt is in operation. There has also been provided a bearing bracket it located below the bearing bracket M at a point above the water line, and in order to brace the tube 8 and maintain it in a vertical position, there have been provided upperand lower bracing rods 29 and 21. The rods 23 extends through the bracket l9 and carry securing nuts 22 and the rods 2i extend through the base 5 and are provided with securing nuts 23. When the nuts 22 are tightened, the tube will be firmly braced and prevented from being moved transversely and broken from the neck I by force of swiftly running water or by drift wood or the like striking the upper end of the tube.

When this pump is in use, the column is erected in a vertical position in a well, river or other body of water with the tube 8 disposed below the level of the water and the column extending upwardly out of the water. This column may be of any desired height and as water is pumped upwardly through the column it will flow through the discharge spout 2 and directly into an irrigation ditch or through a pipe or trough into the irrigation ditch. It will be obvious that the water need not be used for irrigation purposes but could be pumped into a storage tank or the like. Rotary motion is transmitted to the pump shaft through the medium of the belt l8 and the pulley I1 and as this shaft turns in the bearings l5 and E6 the impellers H and I2 will force the water from opposite ends of the tube towards the central portion thereof and through the neck 1 into the hollow column through which it flows to the top of the column and out through the discharge spout. The solid lower portion of the column greatly reinforces the same and also imparts weight which will reduce likelihood of the column tilting out of its vertical position.

Having thus described the invention, what is claimed as new is:

1. In a pump, a vertically disposed column having a discharge at its top, a base having the lower end of said column secured thereto with the base projecting laterally from the column, an inlet neck extending from said column, a tube carried by the outer end of said neck and extending upwardly and downwardly therefrom and open at both ends, a bearing carried by the extended portion of the base under the lower end of said tube, bearing brackets extending laterally from said column and spaced one above the other, a shaft extending vertically through said tube axially thereof with its lower end mounted in the bearing of the base and its upper end portion journaled through the bearing brackets, a pulley carried by said shaft, and spirally formed impellers carried by said shaft within the tube above and below said neck, one impeller being of a right-hand spiral and the other a left-hand spiral whereby during rotation of the shaft water may be forced from both ends of the tube towards the center thereof and through the neck into the column and upwardly through the column to the discharge at the top thereof.

2. In a pump, a base, a vertically disposed column rising from said base and having an outlet at its top and an inlet neck extending laterally thereof from adjacent its lower end, a tube disposed vertically in spaced relation to said column and open at its top and bottom, said neck communicating with the tube intermediate the length thereof, a bearing bracket extending laterally from said column over said tube, bracing rods extending vertically from upper and lower ends of said tube and secured through the bearing bracket and the base, a shaft extending vertically through said tube and rotatably supported by the base and the bearing bracket, propellers carried by said shaft above and below the neck, and means for imparting rotation to said shaft.
